A general, practical, and efficient method for the dimerization of dithiocarbamates has been developed that can be used to prepare the corresponding bis(1-arylimino-1-alkyl/arylthiomethyl) disulfides with dilauroyl peroxide (DLP) as mild oxidant. Notably, a lauroyl radical, rather than an undecyl radical, was established as the radical hydrogen-abstractor during the dimerization process. The amount
已开发出一种通用、实用且有效的二硫代氨基甲酸酯二聚方法,可用于以过氧化二月桂酰 (DLP) 作为温和氧化剂制备相应的双 (1-芳基亚氨基-1-烷基/芳硫甲基) 二硫化物。值得注意的是,在二聚化过程中,月桂酰基而不是十一烷基被确立为自由基吸氢剂。DLP 的量会影响二聚化产率,50 mol-% DLP 产生最高产率的二硫化物。使用过量的 DLP 会产生十一烷基自由基,它会迅速将二硫化物分解为相应的异硫氰酸酯。
